IMPROVEMENT .IN SHEARS.

Specification forming part of Letters Patent No. 43,809, ated August 9, 1864.

T0 all whom, it may concern:

Be it known that 1,1HE0D0EE WALLIS, of the town of Scipio, in Cayuga county and State ot' New York, have invented a new and useful Improvement in Hand-Shears or Nippers; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the aecompanying drawing, and to the letters of ref erenee marked thereon.

The nature of my invention consists in employing a pulley and its connections (to be hereinafter described) between the two levers in machines where compound levers are used for the purpose of largely reducing the friction ofthe joint.-

A side view of the nippers is represented in the drawing with all the parts in their relative position. A lis the lower or single side of said shears. B and G are the two levers on the opposite side. At D in A and E in B` will be seen the cutting-edges. The shears have connections like those represented at F, G, and H on both sides of the levers A and O. The levers C and A are connected by the piece F, and the levers B and G are joined by the two connections G and H through the center of pulley I. It will be noticed that one side ofthe pulley` I rests in a curve in the end of'the lever B, whose radius equals the radius 4ot the pulley I. It will be obvious that this The pulley I and the connections G and H, l

in combination with levers C and B, as set forth.
